While its sealed-case limitations will turn off power users, Apple's least expensive Mac delivers a solid OS X experience in a compact box with similar performance to the entry-level MacBook Air and iMac models.

Apple skips 4K and goes directly to what the company calls a 5K display in this expensive, extravagant all-in-one iMac desktop that will appeal to photo and video professionals -- or anyone else looking for the best possible screen resolution.

While it includes some performance and graphics concessions on the lowest priced model, the 21.5-inch iMac brings Apple's iconic design and top-notch bundled accessories and software to a wider audience.

A refreshing new way to look at all-in-one desktops, the Lenovo B750's Blu-ray-friendly, extra-wide display is great for movies (if you add some extra software), and games greatly benefit from a wider field of view. It's different, and fun to use, but it cries out for a touch screen.
